Abstract:
A request to open a file from a plurality of files in a storage is received from an application. The storage is made up of an index partition, containing recordings of file system indexes, and a data partition, containing recordings of the indexes and the file system data body. A file descriptor is created with an update flag that references the file. A determination is made that the file is being updated by the application, and the update flag is set to a value representing that the file is being updated. A request to write an index of the file system is received. A determination is made whether a specific file from the plurality of files is being updated. The index is written to the storage with an extended attribute for the specific file indicating that the specific file was being updated at the time the index was written.
